This study intends to evaluate the balance ability of Korean adults in their 20s and create balance indicators using digital equipment(FRA 510 S). The study participants participated in 50 men and women in their 20s without musculoskeletal and nervous system diseases. For data analysis, Repeated Measures ANOVA was used. As a result of the study, it was confirmed that the movement of the body weight was higher when the eyes were closed and the test was performed than when the eyes were opened on a flat floor and a balance pad(47cm×39cm×5.5cm). And there was no difference according to the gender of men and women. In a future study, it is considered that the balance ability of normal elderly people will be evaluated, and the balance index of normal adults in Korea will be created and applied to the evaluation of patients with impaired balance ability. 본 연구는 디지털 장비(FRA 510 S)를 활용하여 한국의 20대 정상 성인의 균형능력을 평가하고 균형지표를 만들고자 한다. 본 연구 참여자는 근골격계, 신경계 질환이 없는 20대 정상 성인 남녀 각각 50명씩 참여를 하였다. 데이터 분석은 반복측정 분산분석을 사용하였다. 본 연구 결과 남, 여 모두 평평한 바닥과 밸런스 패드(47cm×39cm×5.5cm)에서 눈을 뜨고 있을 때보다 눈을 감고 검사를 진행하였을 때 체중심의 이동이 많은 것을 확인하였다. 그리고 남, 여 성별에 따른 차이는 없었다. 추후 연구에서는 정상 노인의 균형능력을 평가하여 한국의 정상 성인의 균형지표를 만들고 균형능력이 손상된 환자 평가에 적용이 가능할 것이라고 생각된다.

성견 발치와에 매식한 2종의 Bovine Bone Powder가 치유에 미치는 영향에 관한 조직학적 연구

박태성,임성빈,정진형,김종여,Park, Tae-Seong,Lim, Sung-Bin,Chung, Chin-Hyung,Kim, Jong-Yeo 대한치주과학회 2000 Journal of Periodontal & Implant Science Vol.30 No.3

Several extraction cases with advanced bone loss as a result of periodontal disease, root or labial bone fracture, extensive caries, and periapical lesions occur esthetic, functional problems and severe bone loss. Therefore, to treat these cases used several surgical methods and socket preservation among this therapies have been evaluated simple, effective and good prognosis in the implant placement. Socket preservation therapy have been used with barrier membranes or/and graft materials. Deproteinized bovine bone mineral have been evaluated ideal grafting materials. Recently, calcium-phosphate thin film coated bovine bone powders were developed in our country, but the study for these material wasn't reported. When two types of xenograft materials were implanted in extraction sockets of Beagle dogs, the effects of these were analyzed after 4 weeks and 8 weeks histological views. The results of this study were as follows. 1. In control groups, 4 weeks after implantation, the extraction sockets were filled with connective tissue which has dilated vessels and epithelial growth. And after 8 weeks, irregular connective bundles were observed. But new bone formation was not seen. 2. In Bio-Oss groups, epithelial growth was not seen and bone powder was covered with connective tissue fiber. New bone formation was found around the interproximal bone. There was no special change seen after 8 weeks, connective tissue fibers became more regular, and bone growth near bone powder was not made well. 3. In Ca-P BBP groups, epithelial cells didn't grow in the extraction sockets, there was a lot of new bone made around the bone powder after 8 weeks, new bone around bone powder was replaced with mature bone. It is thought that bone powder grafting into the extraction sockets is very useful for conservation of ridge, and Ca-P BBP is more effective in bone formation than Bio-Oss.

박태성,홍성창 ( Tae Sung Park,Sung Chang Hong ) 한국공업화학회 1998 공업화학 Vol.9 No.2

배출가스중의 SO₂제거를 위하여 다양한 금속산화물로 구성된 천연망간광석, 철광석, CuO/γ-Al₂O₃등을 흡착제로 사용하여 고정층반응기에서 흡착용량실험을 하였다. 또한 흡착제중 흡착용량이 떨어지는 철광석을 제외한 두 가지 흡착제를 이용하여 유동층반응기에서 유속, 온도, 입자크기 등의 조업조건에 따른 SO₂ 흡착실험을 수행하였다. 모든 흡착제에서 온도가 증가할수록 흡착량이 증가하는 화학흡착반응을 보였고 유동층반응기에서 U_0/U_mf및 U_0-U_mf와 같은 유속조건에 따라 입자 크기에 따른 흡착량의 변화가 다르게 나타났으며 유동층반응기 성능식으로부터 반응속도상수를 얻었다. 이 실험을 통하여 천연망간광석이 유동층반응기에서 SO₂ 흡착제로의 사용가능성을 확인할 수 있었다. In a fixed bed reactor, adsorption capacity of SO₂in simulated flue gases was investigated with NMO(natural manganese ore), composed of various metal oxides, iron ore and CuO/ γ-Al₂O₃ as adsorbents. The experiment carried out in a fluidized bed reactor with variables such as gas velocity, temperature and particle size. Iron ore was excluded in the fluidized bed reactor experiment for the lower adsorption capacity. The adsorption of SO₂ in metal oxide is a typical chemisorption because the adsorption capacity of all adsorbents increased with temperature. The effect of particle size on the adsorption capacity was varied with the ratio, U_0/U_mf and the difference of U_0- U_mf. U_0 is the gas velocity, U_mf is the minimum fluidization gas velocity. U_0/U_mf and U_0/U_mf explain the behavior of the gas and solids in the fluidized bed reactor. From the performance equation of the fluidized bed reactor, kinetic reaction rate constants were obtained by the non-linear least square method. The adsorption capacity of NMO proved the potential use of SO₂ adsorbents.

본 연구에서는 초음파원자현미경을 이용하여 비파괴적인 표면탄성이미지 분석과 나노표면에서의 기계적 물성 평가를 연구하였다. 이를 위해 접촉역학 특성에 따른 캔틸레버의 공진주파수 변화를 이론적으로 해석하고 실험적으로 측정하였다. 스프링-질량 모델과 Herzian 이론을 이용하여 계산한 이론적인 접촉 공진주파수는 초음파원자현미경 캔틸레버의 실험적인 접촉 공진주파수의 변화와 매우 유사하였다. 결과적으로, 초음파원자현미경의 표면 높이 이미지와 진폭이미지를 성공적으로 얻을 수 있었고 진폭신호를 통하여 시료 표면에서의 탄성특성을 정성적으로 평가하였다. Nondestructive surface imaging of elastic characteristic and mechanical property has been studied on nanoscale surface with ultrasonic AFM. Resonance frequency variation of cantilever is theoretically analyzed with respect to contact mechanics as well as experimentally measured. The contact resonance frequency is calculated theoretically using the spring-mass and Herzian model in accordance with the resonance frequency of UAFM cantilever measured experimentally. Consequently, the topography and amplitude images could be obtained successfully and the elastic characteristic at the nanoscale surface was evaluated qualitatively by amplitude signals.

The study performed analysis focusing on specialized convention and exhibition facilities among convention and exhibition facilities in Korea. The procedures and results were as follows: First, by theoretical consideration, meaning and contents of convention and exhibition programs done in convention and exhibition facilities were considered and after that, general characteristics of the programs which were the main of space utilization was derived. Second, considering scale and location, 6 facilities were re-selected for in-depth research from 12 facilities investigated preliminarily. Selected facilities were categorized by scale and through the analysis of programs done in this facilities for the last 1 year, overview and characteristics of utilization for exhibition space, conference space, and multi-purpose space, etc were analyzed. Third, through the case study on the programs, individual characteristics of space utilization by convention and exhibition program were analyzed. From the result of the study, considering the whole, the space utilization of programs was done as conference space rather than exhibition space and the ratio of use as conference space to use as exhibition space was 1.8 in the large facilities, 6.7 and 7.6 in the middle facilities and the small facilities, respectively. In the middle and small facilities, the ratio of use of one room as conference space was very high. In the large facilities, there was no big difference with the ratio 50:50 of the programs involving exhibition to other programs, but in the middle and small facilities, the ratio of the former to the latter was observed over 2.4 and 3.6. This fact indicated that the function of use as promotion and communication space for companies and industrial entities which were the essential purposes became low.

이행기 러시아 대학의 변화

박태성(Park, Tae-sung) 아시아·중동부유럽학회 2003 동유럽발칸학 Vol.5 No.1

본고는 러시아 현대사에 커다란 전환을 가져온 두 이행기를 대상으로 대 학의 기능과 역할을 고찰한다. 첫 번째 이행기는 강압적무력적 수단을 동원 한 체제변화가 수반되었고, 두 번째 이행기는 평화적자연적 과정에서 이루 어진 체제 전환기이다. 이렇게 성격이 다른 두 이행기를 같은 틀 속에서 비 교코자 하는 것은 러시아 현대사에서 대학의 기능을 보편화시켜 보려는 의 도라 하겠다. 전제정의 몰락과 함께 찾아온 사회주의 체제에 대학인들은 쉽게 적응할 수 없었다. 더욱이 짜리 정부의 전향적인 움직임을 주도했던 대학 교수들의 입장에서는 볼쉐비끼의 강압적인 평등교육 지향의 정책을 수용할 수 없었 던 것이다. 첫 이행기에 나타난 대학인의 반응은 보수적, 수구적 성향이 다 분했고, 대학의 역할 또한 적극적인 순기능을 보인 것은 아니었다. 사회주 의에서 시장경제로의 이행기에서 보여준 대학인의 반응은 보다 적극적이었 다. 그러면서도 사회 어느 계층보다 보수적이며 안정 지향적인 태도를 보였 으며, 도덕적 기반도 범기독교적 가치관에서 벗어나지 않았다. 이 시기에도 대학의 분위기가 사회체제의 변화를 주도하지 못했음을 상기할 때, 소극적 인 순기능 역할밖에 하지 못함을 알 수 있다. 이행기 러시아 대학의 변화양상을 통해 보편적인 진리를 재확인할 수 있 다. 대학과 학문의 발전 틀은 국가가 마련하는 것이지만, 그 용량은 대학인 스스로가 채워나가야 한다는 점이다. 국가의 간섭은 결코 대학발전을 가져 다주지 못하며, 오히려 진보적 지식인의 반발만 야기할 뿐이다. 국가로부터 진정한 대학자치가 보장될 때 대학의 발전이 가능하다. 물론 대학인의 집단 이기주의도 대학발전의 저해요인인 만큼, 변혁을 주도하는 개혁세력의 환 골탈태한 모습이 요구된다는 것이다. This paper deals with the change of Russian university in transitional age. The first transitional age changed higher education system by enforcement and radical methods after Russian revolution. The second transitional age transformed higher education system in the peaceful and gradual environment of market-economy system. The economic crisis affecting all public institutions has had a devastating impact on both education and science in Russia. In place of Soviet attempts to plan admissions, the new system is designed to be much more sensitive to student demand. During periods of massive change, winners and losers appear with stunning rapidity. For the first time since the revolution, the creative potential of the population may now be given free rein. Few expect miracles, but it is not unreasonable to expect positive results within the next decade. However, these positive results are likely to be seen only at a limited number of institutions, particularly in the elite universities that have already been involved in experiments and reforms. During the transition it will be important to remember that all nations have a range of higher educational institutions. The Russian problem has been twofold: The human and intellectual contributions from the best universities were poorly used; and the drop-off below the level of the elite institutions was quite steep. If the elite institutions are given the conditions to make a larger contribution, the longer-term impact might be an economy that could better support a broader range of schools.

박태성(Tae-Sung Park),곽동열(Dong-Ryul Kwak),박익근(Ik-Keun Park),Chiaki Miyasaka 한국비파괴검사학회 2012 한국비파괴검사학회지 Vol.32 No.4

최근 나노 박막은 MEMS/NEMS, 광학 코팅, 반도체 산업 등 다양한 분야에서 사용이 되고 있다. 박막은 마모, 침식, 부식, 고온 산화를 방지하기 위한 목적으로 사용될 뿐 아니라 특성화된 자기, 유전적 특성을 만들기 위한 목적으로 사용된다. 많은 연구자들이 이러한 박막 구조의 특성(밀도, 입자 크기, 탄성 특성, 필름/기지 계면의 특성)을 평가하기 위하여 많은 연구를 진행하고 있다. 이들 중에 박막과 기지 사이의 접합 특성을 평가하는 것이 많은 연구자들의 주 관심사가 되어 왔다. 본 연구에서는 나노 박막의 접합 특성을 평가하기 위하여 각기 다른 접합 특성을 가지는 폴리머 박막 시험편을 제작하였다. 제작된 시험편의 접합 특성을 측정하기 위하여 초음파현미경의 V(z) 곡선법을 이용하여 표면파의 속도를 측정하였다. 또한 계면을 포함하는 시험편의 표면을 전파하는 표면파의 속도와 접합력의 상관관계를 확인하기 위해 나노 스크래치 시험을 적용하였다. 그 결과 초음파현미경을 이용하여 측정된 표면파의 속도와 나노스크래치 시험을 이용한 임계하중이 일치하는 경향성을 나타내었다. 결론적으로 초음파현미경의 V(z) 곡선법은 나노 스케일 박막 계면에서의 접합 상태를 평가할 수 있는 기법으로 그 가능성을 나타내었다. In recent years, nano-structured thin film systems are often applied in industries such as MEMS/NEMS device, optical coating, semiconductor or like this. Thin films are used for many and varied purpose to provide resistance to abrasion, erosion, corrosion, or high temperature oxidation and also to provide special magnetic or dielectric properties. Quite a number of articles to evaluate the characterization of thin film structure such as film density, film grain size, film elastic properties, and film/substrate interface condition were reported. Among them, the evaluation of film adhesive to substrate has been of great interest. In this study, we fabricated the polymeric thin film system with different adhesive conditions to evaluate the adhesive condition of the thin film. The nano-structured thin film system was fabricated by spin coating method. And then V(z) curve technique was applied to evaluate adhesive condition of the interface by measuring the surface acoustic wave(SAW) velocity by scanning acoustic microscope(SAM). Furthermore, a nano-scratch technique was applied to the systems to obtain correlations between the velocity of the SAW propagating within the system including the interface and the shear adhesive force. The results show a good correlation between the SAW velocities measured by acoustic spectroscope and the critical load measured by the nano-scratch test. Consequently, V(z) curve method showed potentials for characterizing the adhesive conditions at the interface by acoustic microscope.
